Question

High waves caused by movement under the sea ocean

Answer 1

The high waves caused by movement under the sea or ocean are called as Tsunami waves.

Explanation:

• Tsunami is derived from two Japanese words, Tsu meaning harbour and nami meaning waves, therefore the term means Harbour Waves.
• Any sudden motion in the ocean floor generates these tsunami waves.
• These high waves are generated primarily due to two reasons: an underwater earthquake and volcanic eruptions.
• But it can also be caused by underwater landslides.
• Or also by a large meteorite, which when hits the ocean surface can generate these tsunami waves.
• The Indian Ocean tsunami on 26th December 2004 was caused by an underwater earthquake.
